In the ground, there is an additional 30% of freshwater. Less than 1/150th of one percent, or 22,300 cubic miles (93,100 cubic kilometers), of the world's fresh surface water comes from rivers and lakes. The latest research reveals that underground water is the greatest store of water on land, measuring 44 million cubic kilometers and exceeding the amount of Earth's ice sheets. When combined with earlier estimations of shallower groundwater. Most of that three percent, according to the U.S. Geological Survey, is inaccessible.

Rocks formed from materials eroded from already existing rocks, from the evaporation of water, from the hard outer shells of marine organisms, or from decomposing vegetation are called sedimentary rock.
Sedimentary Rock Formation ProcessThe process of forming sedimentary rocks involves four main processes, namely weathering, transportation, deposition, and compaction. The following is the process of formation of sedimentary rocks:
1. Weathering
Is the breakdown of rock, soil, minerals, and wood and man-made materials through contact with the Earth's atmosphere, waters, and biological organisms. Weathering occurs in place of origin with little or no movement.
Weathering involves the movement of rocks and minerals by agents, such as water, ice, snow, wind, waves, and gravity to be transported and stored in other locations. There are three important classifications of weathering processes, namely physical, chemical and biological weathering.
a. Physical Weathering, is a weathering process that involves direct contact with atmospheric conditions, such as heat, water, ice, and pressure.
b. Chemical weathering is weathering due to the direct effects of atmospheric chemicals or biologically produced chemicals.
c. Biological Weathering, is weathering caused by living things and caused by the processes of animal, plant and human organisms.
2. Transportation
The process of transporting material from the place of origin to the place of deposition. This process requires transportation agents in the form of gravity, wind, glaciers, and water.
3. Precipitation
Sedimentation is the geological process when sediments resulting from weathering processes or soil and rock are added to a lower lying area transported by wind, glaciers, water, and gravity.
4. Compaction and Cementation
Compaction occurs when sediments are buried deeply, placing them under pressure due to the weight of the layer above them.
Meanwhile, cement is a new mineral that attaches to sediment grains like cement binds sand grains to building materials.

1) Describe the formation process of igneous rocks.
2) What is a metamorphic series?
3) What is regional metamorphism?
4) What is the difference between low-grade and high-grade metamorphic rocks?
Answer:
1. Igneous rocks form when hot, molten rock crystallizes and solidifies. The melt originates deep within the Earth near active plate boundaries or hot spots, then rises toward the surface.
2. Metamorphic series include the Barrovian and Buchan series of metamorphic rocks. George Barrow was a geologist in Scotland who discovered the Barrovian series.[1] These are also called metamorphic facies series. A metamorphic facies series is a sequence of metamorphic facies which plot in a temperature-pressure diagram along a line, and this line represents a certain geothermal gradient. They are not the same as metamorphic zones, as these are defined as a region on a geological map where the pressure-temperature conditions for an index mineral (a mineral that indicates the approximate metamorphic grade of a rock), were appropriate for these minerals to form.
3. Regional metamorphism is metamorphism that occurs over broad areas of the crust. Most regionally metamorphosed rocks occur in areas that have undergone deformation during an orogenic event resulting in mountain belts that have since been eroded to expose the metamorphic rocks.
4. Low-grade metamorphic rocks tend to be fine-grained (the newly formed metamorphic mineral grains that is). High-grade metamorphic rocks tend to be coarse-grained

crushed stone quarries are typically located near cities and towns. group of answer choices true false
True. A quarry is a location where rocks, sand, or minerals are taken from the Earth's surface. Due to its accessibility to the Earth's surface, a quarry is a form of mine known as an open-pit mine.
An underground network of tunnels or shafts makes up a sub-surface mine. Quarries are most frequently used to extract stone for construction purposes. For thousands of years, people have used quarries. Large limestone and granite stones that were manually cut from adjacent quarries were used to construct the Great Pyramids by the ancient Egyptians. These blocks weigh many tons each. The extraordinarily difficult task of stone cutting in marble, granite, and limestone quarries was sometimes put upon slaves and criminals in ancient Rome. Quarrying was substantially more labour when it came to building materials. stones had to be hand pulled or carried out of quarries. Using pulley systems with ropes and movable wooden rails or sleds, stones could also be transported. Thousands of slaves and other labourers were frequently used in this operation. These moai statues were made of stones that was transported from a quarry to various locations on the island. The largest moai is 86 tons in weight. How these prehistoric Polynesian people transported their quarries rock is still being researched by scientists.

what is the rock cycle? explain how one rock type can eventually become a different rock type over millions of years.
A rock cycle is a fundamental concept that shows the transitions among the three basic rock types (metamorphic, igneous and sedimentary).
The rock cycle is a fundamental geological concept that describes transitions through geologic time between the three major rock types: sedimentary, metamorphic, and igneous. When a rock type is forced out of its equilibrium conditions, it changes.
When exposed to the atmosphere, an igneous rock such as basalt may break down and dissolve, or it may melt as it is subducted beneath a continent. Rocks do not remain in equilibrium as they encounter new environments due to the driving forces of the rock cycle, plate tectonics, and the water cycle.
The rock cycle describes how the three types of rocks are related to one another and how processes shift from one type to another over time.

geologists have extracted a drill core at point y for study. how many separate episodes of glaciation can be observed in the core?
Based on the information provided, it appears that there are three (3) separate episodes of glaciation that can be observed in the drill core at point Y.
The core contains three layers of till (a type of sediment deposited by glacial ice) that are separated by two paleosols (ancient soil layers). Each of the till layers contains erratics (rock fragments of different types) that suggest they were deposited by different glacial advances. The first till layer contains W1 and W2 erratics, the second till layer contains IL erratics, and the third till layer contains P2 erratics.
Therefore, the presence of three distinct layers of till with different types of erratics indicates that there were at least three separate episodes of glaciation in the area. The correct answer is therefore c. "3 glacial advances."
